Dr. Collins on bioidentical hormone therapy, one of the most common paths into his practice.
Hormone symptoms, fatigue, mood changes, weight shifts, low libido, sleep disruption, are common, vague, and easy to attribute to something else. A standard annual visit often includes limited hormone testing and limited time to investigate a pattern that unfolds over months or years, which is part of why hormone imbalances go undiagnosed or dismissed as normal aging.
Dr. Drew Collins, ND has practiced naturopathic medicine since 1984 and now treats hormone imbalance in women and men in Bend, Oregon. He uses comprehensive testing that looks at estrogen, progesterone, testosterone, thyroid hormones, and cortisol together rather than one value in isolation. That fuller picture is what allows for a treatment plan actually built around your hormone profile, not a guess based on symptoms alone.
Hormone care at Proactive Choice includes bioidentical hormone replacement therapy, thyroid treatment, testosterone replacement for men, and support through perimenopause and menopause, matched to what your testing actually shows.
Hormones are drugs, and sometimes the testing shows you don’t need them. That’s a fine outcome.
Cleveland Clinic says bioidentical hormones may not be safe if you have a history of, or a high risk for, blood clotting disorders, heart disease, breast cancer or stroke. Hormone therapy has also been linked to blood clots, stroke and gallbladder disease, and the risk of heart disease and breast cancer can rise with age or long-term use.
For men, the Endocrine Society’s guideline advises against starting testosterone if you have breast or prostate cancer, a prostate nodule, a high PSA that hasn’t been looked into, an elevated hematocrit, untreated severe sleep apnea, uncontrolled heart failure, a heart attack or stroke in the last six months, or a clotting disorder, or if you’re hoping to father a child soon. The full list is on our testosterone therapy page.
If you fit one of these groups, hormone therapy isn’t automatically off the table for every hormone, but it’s a longer conversation, and it may need your cardiologist or oncologist in it. Thyroid treatment is a separate question; see hypothyroidism care.
Estrogen, progesterone, testosterone, thyroid, and cortisol are evaluated together rather than one value at a time.
Hormone imbalance is evaluated and treated across the full range of patients, not just one demographic.
Bioidentical hormone therapy is an option when your labs and history support it. Some bioidentical products are FDA-approved and some are compounded, so ask which kind you would be prescribed.
Testing goes beyond a single annual snapshot to understand your actual hormone pattern over time.
Dr. Collins has practiced since 1984, and hormone care is one of the most common reasons patients come to see him.
Hormone treatment is considered alongside your thyroid, adrenal, and overall metabolic health, not in isolation.
A full hormone panel, estrogen, progesterone, testosterone, thyroid, and cortisol, rather than a single limited lab value.
Your results are reviewed alongside your symptom history and timeline, not just compared to a standard reference range.
A plan drawing from bioidentical hormone therapy, thyroid treatment, or other options matched to your specific hormone profile.
Hormone levels are rechecked and your plan adjusted as your body responds and your needs change.
It starts with the free 10-minute phone consultation. If hormones look like the likely problem, the next step is blood work, and recent results from another doctor can often be reused.
A typical panel looks at estrogen, progesterone, testosterone, thyroid hormones and cortisol side by side. One number inside the normal range doesn’t settle much on its own. The pattern, read against your symptoms and timeline, is what matters. For the details, read which hormone tests actually matter.
If you start treatment, your levels are rechecked and the dose adjusted. How often depends on the hormone: for men on testosterone, the Endocrine Society guideline calls for checking testosterone, hematocrit and prostate cancer risk during the first year. Common side effects of bioidentical hormones include breast tenderness, bloating, headaches, spotting and mood swings, and those are worth reporting early rather than waiting for the next visit.

Persistent fatigue, mood changes, weight shifts, low libido, sleep disruption, and irregular cycles are common signs worth investigating, especially if a standard annual visit has not turned up an explanation. A single lab value within normal range does not rule out a meaningful hormone imbalance, particularly for hormones like estrogen and progesterone that fluctuate. A comprehensive hormone panel is the most reliable way to know what is actually happening.
A standard primary care visit typically includes limited hormone testing and limited time to investigate a pattern that unfolds over months. Dr. Collins’ hormone evaluations use comprehensive panels, estrogen, progesterone, testosterone, thyroid, and cortisol together, and more time to connect your specific symptom pattern to what the testing shows. That deeper investigation is often what is missing from a routine annual visit.
Yes. Dr. Collins evaluates and treats hormone imbalance in both men and women, including testosterone replacement therapy for men and bioidentical hormone therapy, thyroid treatment, and menopause support for women. The comprehensive testing approach applies across the board, not just to one patient population.
Yes, bioidentical hormone replacement therapy is one of the treatment options available, using hormones structurally identical to what your body naturally produces, matched to your specific lab results and symptoms. Some bioidentical hormones are FDA-approved and some are compounded, and compounded versions have not been tested by the FDA for safety or effectiveness. Whether it is the right option depends on your individual hormone profile and health history. That is determined through a full evaluation before any treatment plan is built.
No, the practice operates as a self-pay clinic and does not bill insurance directly, though HSA and FSA funds along with credit cards are accepted. This applies to all hormone testing and treatment services. It is worth confirming current pricing directly with the clinic before scheduling.
